Marine Electrical Stern Tunnel Thruster
Application
A marine electrical stern tunnel thruster is a type of propulsion system used in ships and boats to provide additional maneuverability and control. It consists of an electric motor that drives a propeller mounted in a tunnel at the stern of the vessel, perpendicular to the direction of travel. The tunnel surrounding the propeller in the stern thruster provides additional benefits, including protection of the propeller from debris and minimizing the impact of the propeller on water flow, which can increase efficiency and reduce noise and vibration. Electrical stern tunnel thrusters are controlled using a joystick or a computerized system, which allows for precise and smooth maneuvering of the vessel. They can also be integrated with other ship systems, such as GPS and autopilot, to provide seamless operation.
Features
1.Low noise and vibration.
2.Propeller type: Fixed-pitch propeller,Controllable-pitch propeller.
3.Skew blade and large disk ratio, reduce vibration and improve cavitation performance.
4.Underwater structure are optimized so that it have rational construction, which convenient for maintenance and repairing.
5.We can design and manufacture the product according to client's drawing or sample.
We not only provide customers with high-quality products, but also provide complete system solutions and added services for specific customers. Therefore, There are high competitiveness.

Maintenance advice
1. Regularly check whether there is leakage of hydraulic oil in the side thruster of the ship, regularly add tallow to the moving bearings and couplings, and replenish the hydraulic oil of the system in time.
2. Clean the dust in the ship's thruster control panel in time and check the working condition of the ACB.
If the ACB fails to close there are several reasons:
2.1. The control circuit has no electricity;
2.2. The main switch energy storage motor does not store energy normally;
2.3. There is no closing signal to the main switch closing coil;
2.4. The main switch under voltage coil has no electricity.
